Re: Activated complex

The graph is a plot of potential energy (y axis) vs taxon coordinate. Depending if the reaction is endothermic or exothermic, the graph will end at a higher or lower potential energy respectively. The activated complex is the range of energy from the reactant to the peak of the curve. This represent...

Re: determining the catalyst

When you determine the overall reaction by combining the different steps, catalysts are usually in product and reactant side. Intermediates, however, are not in the overall equation because they are made and destroyed in the process.

Re: Final

We're still a ways away from the final, anything Dr. Lavelle mentions in lecture should be remembered like the derivations and such.

Re: Scientific Notation

I think that you should be fine. I do my questions the same way as you, rounding and changing to scientific notation only at the end. Don't think there's any harm at being more accurate.

Re: Hess's Law

For me, I like to think of cancelling things one at a time, and multiplying only if I see fractions.

Re: Heat and thermal Energy

I think that Heat energy is thermal energy during transfer. Thermal energy refers to the internal energy of the system from the temperature.

Re: Combustion Reactions

At room temperature (25 degrees Celsius) I believe that the state of water will be liquid. If I recall correctly it is a gas if the reaction is taking place above boiling point? If I am wrong someone please correct me, I'm also curious.
